Introduction
Have you ever experienced slow internet speeds or connectivity issues? The Domain Name System (DNS) can be the possible culprit. DNS plays a crucial role in connecting you to the internet. Flushing DNS periodically can help address issues with slow internet speeds and connectivity problems. This article will guide you through the process of flushing your DNS to improve your internet performance and security.
What is DNS and Why It Needs to Be Flushed
The Domain Name System (DNS) is responsible for translating web addresses into IP addresses. In simpler terms, it is the system that connects you to the internet. The DNS cache stores the IP addresses of websites and web pages you have visited recently. Over time, this cache can become outdated and cause problems. Flushing your DNS will clear the cache and force your computer to retrieve fresh IP addresses from the internet, ensuring accurate and up-to-date connectivity.
Benefits of Flushing DNS
Flushing your DNS regularly can have several benefits, including:
- Faster internet speeds
- Better performance
- Improved security

- Type “ipconfig /flushdns” in the Command Prompt and press Enter.
